Substitute Part Grouping Explanation

Substitute parts for the S-8261ABCMD-G3CT2U are classified into two categories based on substitution criteria:

Parametric Equivalents (ABLIC Inc. S-8261 and S-8240 Series): These parts maintain identical electrical specifications including Battery Chemistry (Lithium Ion/Polymer), Number of Cells (1), Fault Protection (Over Current, Short Circuit), Operating Temperature (-40°C ~ 85°C), Package (SOT-23-6), Mounting Type (Surface Mount), and compliance certifications (ROHS3, REACH Unaffected). Differences exist only in packaging format (Tape & Reel vs. Cut Tape) and inventory availability. These parts are direct functional replacements.

Similar Parts (Texas Instruments BQ29700DSET and BQ29717DSET): These parts share core functional parameters including Battery Chemistry (Lithium Ion/Polymer), Number of Cells (1), Operating Temperature (-40°C ~ 85°C), and compliance certifications. However, they differ in package type (6-WSON vs. SOT-23-6), supplier device package designation, and provide enhanced Fault Protection (Over Current, Over/Under Voltage, Short Circuit vs. Over Current, Short Circuit only). These require PCB layout and footprint redesign.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same PCB Footprint): Select S-8261AAJMD-G2JT2U or S-8261AAJMD-G2JT2G. Both maintain identical electrical and mechanical specifications to the S-8261ABCMD-G3CT2U. The S-8261AAJMD-G2JT2G offers higher inventory availability (13,700 pcs) in Cut Tape format for lower-volume applications. The S-8261AAJMD-G2JT2U provides Tape & Reel packaging (3,800 pcs) suitable for automated assembly. Both are Active status and ROHS3 Compliant.

For ABLIC Inc. S-8240A Series Substitution: Select S-8240ACS-M6T1U or S-8240ADZ-M6T1U. These maintain identical electrical specifications and SOT-23-6 package compatibility. The S-8240ACS-M6T1U (1,112 pcs) and S-8240ADZ-M6T1U (781 pcs) are both Active status and ROHS3 Compliant. No PCB redesign is required.

For Enhanced Fault Protection with Package Redesign: Select BQ29700DSET or BQ29717DSET from Texas Instruments. These parts provide additional Over/Under Voltage protection beyond the Over Current and Short Circuit protection of the main part. Both use 6-WSON (1.5x1.5) package requiring PCB layout modification. BQ29700DSET (18,360 pcs) and BQ29717DSET (1,854 pcs) are both Active status and ROHS3 Compliant.

Frequently Asked Questions (FAQ)

Q: Can S-8261AAJMD-G2JT2U be used as a direct replacement for S-8261ABCMD-G3CT2U? A: Yes. Both parts share identical electrical specifications, operating temperature range, fault protection capabilities, and SOT-23-6 package. The only difference is packaging format (Tape & Reel vs. original format). No circuit redesign is required.

Q: What is the difference between S-8240ACS-M6T1U and S-8240ADZ-M6T1U? A: Both parts are functionally equivalent with identical electrical specifications and SOT-23-6 package. Differences are limited to inventory availability and internal device designation. Both are suitable for direct substitution.

Q: Why would I select BQ29700DSET or BQ29717DSET instead of ABLIC parts? A: The Texas Instruments parts provide enhanced Fault Protection including Over/Under Voltage monitoring in addition to Over Current and Short Circuit protection. This requires PCB footprint redesign due to different package type (6-WSON vs. SOT-23-6) but offers additional circuit protection capabilities.

Q: Are all substitute parts ROHS3 Compliant? A: Yes. All listed substitute parts including S-8240ACS-M6T1U, S-8240ADZ-M6T1U, S-8261AAJMD-G2JT2G, S-8261AAJMD-G2JT2U, BQ29700DSET, and BQ29717DSET are ROHS3 Compliant and REACH Unaffected.

Q: What packaging formats are available for the S-8261 series? A: S-8261AAJMD-G2JT2G is available in Cut Tape (CT) format with 13,700 pcs inventory. S-8261AAJMD-G2JT2U is available in Tape & Reel (TR) format with 3,800 pcs inventory. Both maintain identical electrical specifications.

Q: Can I use S-8261AAJMD-G2JT2G (Cut Tape) in automated assembly? A: Cut Tape format is suitable for manual assembly or lower-volume production. For high-volume automated assembly, Tape & Reel format such as S-8261AAJMD-G2JT2U is recommended.
